Question

1995monster · Answer

i have no clue what this is

1995monster · Answer

i want an explanation as well

anonymous · Answer

I would assume the 3rd choice, because the others rely on "eyeball" measurements, which are never completely accurate. Connecting two points though requires no measurement.

1995monster · Answer

Ya i didnt expect it to be A because you can't just put a line through it and the other 2 options are just like opposite of each other

1995monster · Answer

can you help me with this one as well http://gyazo.com/e66223dcef475aaed6db1fbf2eaee326

Im really clueless on the 2nd one =/

aum · Answer

The exterior angle of a triangle equals the sum of the opposite interior angles.
Therefore, 15x - 48 = 5x + 12 + 40.

Solve for x first.

1995monster · Answer

so 9?

1995monster · Answer

or at least x = 9

anonymous · Answer

Since it's a triangle:$$\angle M +\angle L +\angle MKL = 180$$
Solve for MKL:$$\angle MKL= 180 - \angle M - \angle L $$
Substitute the values given to you:$$\angle MKL = 180 - 40 - (5x + 12) = -5x + 128$$
To solve for x, use the fact that $$\angle MKL + \angle JKM = 180$$$$-5x+128 + 15x - 48 = 180$$$$x = 10$$So $$\angle MKL = -5(10)+128 = 78$$

wow... ima need to reread that so much i didnt know :P

1995monster · Answer

wait isnt <MKL a traingle itself? so how could <M + <L + <MKL make sense

anonymous · Answer

No <MKL is just a single angle - the one you get by drawing a line from M to K and another from K to L.

anonymous · Answer

It's written that way to make it discernible from <MKJ

1995monster · Answer

OHHHHHHHHHHHHH okie i get it now it was an angleee

1995monster · Answer

Wow thanks for the help appreciate it man
